” title=”- 10 Lack of calcium in the body symptoms and signs”>One of the most important macronutrients involved in the life of the body is calcium. It is present in almost all living organisms, starting with the simplest. Lack of calcium in the human body leads to serious health problems.

The role of calcium in the human body

Calcium plays the most important role in the human body from birth. The calcium content in the body averages almost 1,2 kg of metal, which constantly interacts with the body, giving it and returning again about 800 mg of Ca + daily.

This element is involved in the construction of bone tissues of the body, provides the strength of bones, nail plates, hair, is contained in the enamel of the teeth, thereby protecting them from destruction.

  • Calcium ions are present in cells and participate in energy metabolism,
  • Calcium is involved in the mechanism of muscle contraction (including the heart), controls the heartbeat,
  • It is present in the synthesis of neurotransmitters that transmit nerve impulses by activating certain enzymes.
  • Regulates blood pressure along with other nutrients – magnesium, sodium and potassium,
  • As a catalyst for vitamin K, it participates in the process of blood clotting,
  • Promotes the transport of nutrients, acts on the permeability of cell membranes.
  • Strengthens the connective tissues of the body.

Part of the element is excreted from the body. In order to constantly maintain the required level of calcium in the blood and in the body, it is required to systematically fill the lack of calcium.

In bone tissue, it is represented by calcium phosphate, a crystalline salt of phosphoric acid.

In a nursing infant, the amount of Ca nutrient is approximately 30 grams. As it grows up, the amount of this element in the body also increases, and by the time of puberty its amount will reach 1-1,2 kg. A child should receive 100, and in adolescence 150 mg of calcium daily for the normal development of the skeleton and the whole body. In adults, the intake is 280 mg Ca for men and 200 mg for women.

The daily requirement for calcium increases

during pregnancy and breastfeeding,

during the use of corticosteroid drugs and anabolic steroids,

with increased sweating, in the summer,

Calcium levels in women are affected by menopause; men begin to lose this element from the age of 65. Many people believe that its loss is associated with the fact that older people “grow” downward, become shorter. In fact, this is not the case: the decrease in growth occurs due to the flattening and dehydration of the intervertebral discs.

Why does “calcium hunger” occur in the body?

If you determine the common causes of calcium hunger, then there are only two of them:

  • low levels of macronutrients in food,
  • Reduced absorption of calcium by the body.

With the first reason, everything is clear: to replenish the element, you need to use more products containing this element. Let’s take a closer look at the second reason. Why does the body refuse to absorb calcium? After all, this chemical element is needed by the body.

The problem lies in our diet, which creates an acid-base balance. Excessive consumption of protein products (sausages, smoked meats and other delicacies) leads to acidification of the body. Calcium, having basic or alkaline properties, neutralizes unnecessary acids, forming insoluble salts. But such calcium is bound and does not participate in the life of the body. Part of insoluble salts is excreted from the body, and part is deposited in organs and cells in the form of lime deposits, forming sand and stones, and blood clots and blood clots in the blood vessels.

Detonic – a unique medicine that helps fight hypertension at all stages of its development.

Detonic for pressure normalization

The complex effect of plant components of the drug Detonic on the walls of blood vessels and the autonomic nervous system contribute to a rapid decrease in blood pressure. In addition, this drug prevents the development of atherosclerosis, thanks to the unique components that are involved in the synthesis of lecithin, an amino acid that regulates cholesterol metabolism and prevents the formation of atherosclerotic plaques.

Detonic not addictive and withdrawal syndrome, since all components of the product are natural.

Detailed information about Detonic is located on the manufacturer’s page

The effect of vitamin D on calcium balance

Vitamin D is a group of biologically active substances. The main ones in it – cholecalciferol (D3) and ergocalciferol (D2) provide the absorption of calcium and phosphorus in the small intestine. Thus, a deficiency of vitamin D in the body causes a lack of calcium. Cholecalciferol is synthesized under the influence of ultraviolet (sun) rays, therefore, in the summer you should not miss the opportunity to be outdoors, bask in the sun and sunbathe a little (without fanaticism). Ergocalciferol is found in eggs, sea fish, and cream. Thus, by drinking a glass of non-skimmed milk, a person receives both calcium and vitamin D, which contributes to the absorption of the metal.

” title=”- 12 Lack of calcium in the body symptoms and signs”>Effect of magnesium on calcium

Magnesium and calcium are considered antagonists, however, magnesium interacts with calcium to regulate blood vessel tone and participate in muscle contraction. Calcium affects smooth muscle contraction, while magnesium, on the contrary, relaxes the muscles and dilates blood vessels. Magnesium influences hormones that control calcium metabolism and the absorption of macronutrients by the body. An optimal diet should contain calcium and magnesium in a 2: 1 ratio. Magnesium also maintains the electrolytic potential of the intercellular membranes, facilitates the penetration of calcium, sodium and potassium ions through them.

Symptoms and signs of calcium deficiency

When the body lacks calcium for vital functions, it takes it from the skeleton. Deficiency of an alkaline element is observed in women during pregnancy. Many people lose their teeth during this period – they become more sensitive and begin to crumble. By the way, traditional medicine recommends a simple and completely harmless way to replenish Ca. Take a few eggs, wash them thoroughly with warm water and boil. It is recommended to drink water from boiled eggs to replenish the element. And eggs will always be used in some salads, morning breakfasts for the whole family.

Lack of calcium in the body is observed during menopause, symptoms in women during this period are manifested by osteoporosis, fragility of bones.

With hypocalcemia, the following symptoms and signs are observed:

  • Increased nervous irritability, irritability, insomnia
  • Calf muscle cramps, tingling in the arms and legs,
  • Joint pain, sore gums,
  • Heavy menstruation in women
  • Hypertension and tachycardia,
  • Dental problems
  • Brittle nails, brittle and weak hair,

Signs of calcium deficiency have symptoms similar to other pathologies, for example, seizures and insomnia are observed with magnesium deficiency. And in order to identify the problem, you should not self-medicate, but you must undergo an examination and consult a doctor.

Symptoms of hypocalcemia in children are expressed by the fact that children who lack calcium eat chalk and even earth. Bans won’t help. To make up for the lack of calcium, it is better to buy calcium gluconate or glycerophosphate tablets for your child.

Diseases caused by calcium deficiency

Lack of calcium in the body is the cause of such pathologies as:


What is hypocalcemia? This syndrome implies a low Ca content in the blood. It leads to decreased blood clotting and bleeding. Hypocalcemia occurs for the following reasons:

  • a decrease in the level of Ca + ions
  • renal failure
  • rapid rise in phosphate levels,
  • acute pancreatitis,
  • The use of certain Ca-lowering drugs.


This pathology is caused by a lack of calcium phosphate salts in the bones. This syndrome can appear in childhood, and leads to disability, since soft, low-Ca bones are prone to fragility.


This disease is characterized by a violation of the structure of bone tissue, a decrease in bone density, the predominance of decay over the process of bone formation. The risk of bone fractures increases. It is classified as an metabolic disease of the musculoskeletal system. Women of menopause are more likely to be affected by this pathology.

Dysfunction of the thyroid and parathyroid glands, as one of the causes of low calcium in the body.

The thyroid gland, along with thyroid hormones, produces thyrocalcitonin, or, as it is commonly called, calcitonin, a hormone involved in calcium-phosphorus metabolism. Calcitonin also activates the work:

  • Osteoclasts – multinucleated cells that, by dissolving minerals and breaking down collagen, destroy and remove old bone tissue,
  • osteoblasts – young cells that generate bone tissue. Osteoblasts are involved in the deposition of calcium salts in the intercellular substance, and matrix calcification occurs.

The four small parathyroid glands are located at the back of the thyroid gland and are responsible for the amount of calcium in the body and for the normal functioning of the nervous and motor systems. When the level of calcium in the blood drops below a specific level, the receptors of the glands are excited and release parahormone into the blood, which, in turn, stimulates osteoclasts to release the metal Ca from bone tissue.

Dysfunction of the parathyroid glands leads to a disruption in hormone production, which in turn leads to calcium-phosphorus imbalance, and the development of endocrine diseases.

How and how to compensate for calcium deficiency?

People suffering from joint pain and fragility of bones are concerned about the question: how to increase calcium in the body?

  • It is necessary to ensure a sufficient intake of Ca and vitamin D with food during menopause and men over 50 years old. The daily intake of calcium should be 1200-1500 mg.
  • Reduce or quit drinking coffee, smoking, alcohol
  • Elements – phosphorus, potassium and magnesium are also involved in the process of absorption of calcium and its metabolism, so their intake must be balanced.

Treatment of hypocalcemia is aimed at eliminating nutrient deficiencies and the resulting consequences of this deficiency.

Not the last place is occupied by the question of how to increase calcium in the blood, but so as not to overdo it and not to provoke the formation of blood clots? Products containing this alkaline earth metal pass from the stomach into the intestines, where, after appropriate chemical reactions, individual macro and microelements enter the bloodstream, which carries them in the right amount to bone tissues and body cells. And vitamin D and other nutrients are needed to keep calcium from turning into hard limescale.

Milk products. 1 glass of milk or kefir provides 25-40 percent of the daily calcium requirement. If you want the Ca nutrient to be better absorbed by the body, do not be afraid to drink natural products, without defatting. Together with fats, vitamin D is lost. And there will be a minimum of calcium in refined and low-fat foods.

Chicken eggs provide 15 percent of the daily need for vitamin D, but calcium is contained in its shell. There is little nutrient in the product itself – about 4%.

Spinach greens contain 10% of the daily value of Ca. In the Caucasus, one of the favorite everyday dishes is an omelet with spinach. This dish not only replenishes the calcium balance, but also ensures its absorption.

Beans are generally striking in their abundance of nutrients. Ca it contains 15 percent of the daily value, but beans contain 25% magnesium, 60% phosphorus, 32% iron.

Parsley provides a quarter of the daily value. Magnesium (21%) and phosphorus (12%) present immediately help the absorption of the alkaline nutrient.

Lack of calcium, of course, negatively affects the state of health and well-being. But this does not mean at all that if you find these symptoms and signs of calcium deficiency in your body, you will run to the pharmacy, pick up various dietary supplements and vitamin complexes and swallow everything. The system is needed in everything, and an excess of calcium is no less dangerous than its lack. Therefore, before you start drinking “medicines for all diseases”, you should consult with your doctor. Perhaps you have not hypercalcemia at all, but a deficiency of other nutrients, or another pathology.
